漆树是多年生的乔术树种,用常规选种方法往往需要较长的时间。为缩短选种年限,提高选种效果,研究漆树产漆量的早期预测课题就显得十分必要。目前,从事漆树选种工作者,多是研究以成龄漆树流漆量的多少来确定品种的优劣,而用几种方法同时进行苗期流漆量的测定,以预测品种优劣的报道还未见。1981年以来,我们从事了这方面的研究。开始是对1、2年生的漆树苗木,采用半叶法和漆液带法,并结合径、高生长量法进行产漆量的早 Lacquertree is a perennial tree species, with the conventional selection method often takes longer time. In order to shorten the time of selection and improve the effect of seed selection, it is necessary to study the early prediction of lacquer yield. At present, the selection of lacquer tree workers, mostly to study how much the flow of lacquer tree flow to determine the pros and cons of varieties, and using several methods at the same time the flow of seedling flow measurement to predict the pros and cons of the report Not yet seen. Since 1981, we have been engaged in this aspect of research. The beginning of the 1, 2-year-old lacquer seedlings, the use of half-leaf method and the liquid paint with law, combined with diameter, high growth rate of the amount of paint production early
